| Popis: | Qarounispora grandiappendiculata Nourel-Din, Abdel-Aziz & Abdel-Wahab, sp. nov. (Figure 2) MycoBank number: MB 841142 Etymology:��� In reference to the large-sized polar appendage to the ascospore. Type:��� EGYPT. El-Faiyum governorate: Qaroun Lake, on decaying submerged wood, 29�� 29��� 00��� N 30�� 49��� 09��� E, 20 November 2018, Coll. A. A. H. Nourel-Din (SUMCC H-17009, holotype). Ascomata 125���200 ��m in diameter (x = 166.5 ��m, n = 7), perithecial, ostiolate, papillate, superficial or partly immersed, globose to subglobose, yellow to orange-brown in color, membranous. Neck 50���90 ��m long, 45���60 ��m diam., cylindrical to conical, hyaline to yellow-orange, periphysate, ascospores ooze from the ostiolar canal forming spore mass that is bright yellow-orange in color. Peridium 12.3���22.8 ��m thick, membranous, one-layered, yellow to orange-brown in color, forming textura angularis. Catenophyses present. Asci 65���115 �� 30���45 ��m (x = 86 �� 38 ��m, n = 6), unitunicate, thin-walled, without an apical apparatus, eight-spored, developing at the base of the ascomatal venter, semi-persistent, clavate or broadly ellipsoidal. Ascospores 18���40 �� 13���18 ��m (x = 27 �� 14 ��m, n = 50), hyaline to yellow-orange in color, thick-walled, distoseptate, one septate, not constricted at the septum, ellipsoidal to broadly ellipsoidal. Appendages present, one polar appendage coiled inside a globose sheath connected with the ascospore by a hyaline rib and the appendage swell in water to form irregular amorphous large structure 20.3���59 �� 14���24.2 ��m. Notes:��� Qarounispora grandiappendiculata is characterized by having yellow to orange, superficial or partly immersed, membranous ascomata, one layered peridial wall, semi-persistent asci, one-septate, thick-walled, distoseptate, hyaline to yellow-orange, broadly ellipsoidal ascospores with amorphous, large and irregular one polar appendage.
